Director/PDMR Shareholding

LTIP Options to Directors and RSA Options to PDMRs

The Company announces that on 23 October 2026 under the Company's Long Term Incentive Plan (the "Plan"), that the Directors and Persons Discharging Management Responsibilities ("PDMR") listed below were granted nil-cost share options (each an "Option") over Ordinary Shares of 2p each in the Company ("Shares") as follows:

Each Option was granted pursuant to the Plan approved by shareholders in December 2016 and amended by the Board in accordance with paragraph 19.2 of the Plan, in September 2023.

No consideration was paid for the grant of the Options. The number of Shares subject to each Option was calculated based on a share price of 283.1p, being the average mid-market closing price, as derived from the London Stock Exchange daily Official List, from the five-days prior to the grant.

For Graham Prothero and Andrew Kirkman, vesting of each Option is conditional upon achieving certain performance targets over the three-year performance period ending 30 June 2029 and continued service (save for good leaver treatment) through to the assessment of the performance targets. Full details of the relative TSR and carbon reduction performance targets are disclosed in the Company's FY26 Annual Report.

At the time the FY26 Annual Report was published, the Board had not determined the EPS performance target, relating to 50% of such performance based Options. The EPS target has now been determined and reflects the Company's ambitious internal plan in a backdrop of continued sector uncertainty, as well as a material change in earnings expectations for shareholders.

Full details of the EPS performance target for the year ended 30 June 2029 applicable to such performance based Options are set out below:

* Straight-line vesting between threshold and maximum performance.

To the extent they become vested, the Options will normally become exercisable when Company announces its financial results for the financial year ending 30 June 2031.

For the PDMRs the Options are subject to a performance underpin condition and a continued service requirement through to the time vesting of the Options. To the extent they become vested, the Options will normally become exercisable when Company announces its financial results for the financial year ending 30 June 2029.
